Young Teacher from the Department of Physics Published Collaborative Research Achievements in Nature Communications

Recently, Wang He, a teacher from the Department of Physics of our university, collaborated with Professor Wang Jian's research group, Academician Xie Xincheng's research group, Professor Jia Shuang's research group, Professor Gao Peng's research group from Peking University, as well as Professor Jiang Hua from Soochow University and Professor Wang Ziqiang from Boston College, to publish important scientific findings on superconductivity in topological-kagome-magnet/metal interface as the first author in the renowned academic journal Nature Communications. The paper is titled "Emergent Superconductivity in Topological-Kagome-Magnet/Metal Heterostructures".

Wang He's research group and collaborative research group discovered interface superconducting states in the topological kagome magnet TbMn6Sn6 (kagome magnet)/non-superconducting metal Heterostructures (Fig. 1). The superconducting state magnetoresistance curve exhibits the hysteresis phenomenon, indicating its coexistence with ferromagnetism. The anisotropy of the superconducting critical field indicates that the superconducting state is quasi-two-dimensional. Meanwhile, the system has a strong spin-orbit coupling. The above three characteristics are important conditions for generating two-dimensional chiral topological superconductivity. Therefore, the interface superconducting state is highly likely to be a two-dimensional chiral topological superconducting state. This work not only provides a new experimental platform for studying topological superconductivity, but also provides a practical and feasible experimental scheme for the implementation of topological superconductivity. In this work, Wang He's research group was funded by Beijing Municipal Natural Science Foundation, Beijing Municipal Education Commission Project Fund, and School of Interdisciplinary Studies of Capital Normal University.
